Description

Technical Field

[0001] The present invention relates to the technical field of water meters, and in particular to a copper-sealed Internet of Things water meter. Background Art

[0002] At present, smart IoT water meters have been widely used in property communities, industrial and mining enterprises, schools and institutions. Most common IoT water meters on the market are composed of a base meter and an electronic part. The electronic part and the base meter are connected by a communication line, which is cumbersome in structure. In addition, the water volume metering unit of some water meters adopts a non-magnetic or magnetic separation structure, which is easy to be interfered by humans, affecting the accurate measurement of the water meter; moreover, most water meters on the market currently have poor waterproof performance. After long-term use, water flow can easily penetrate into the core of the meter from the outer shell, causing damage to the circuit part of the core, affecting the normal use of the water meter. Summary of the invention

[0003] In view of the defects in the prior art, the present invention provides a copper-sealed Internet of Things water meter to improve the waterproofness of the water meter and the accuracy of water measurement.

[0004] The present invention is achieved through the following technical solutions:

[0005] A copper-sealed Internet of Things water meter comprises a case, a filter screen is fixed inside the case, a base is fixed inside the filter screen, an impeller is arranged inside the base, a magnet is fixed to the upper end of the impeller, an outer cover is arranged above the impeller, a groove is arranged at the bottom of the outer cover, the magnet at the upper end of the impeller extends into the groove, a copper inner cover is fixed inside the outer cover, a watch movement is installed inside the inner cover, the watch movement comprises a mounting frame, a circuit board is fixed inside the mounting frame, a dial is fixed above the mounting frame, a gear shaft I is installed at the bottom of the mounting frame, the gear shaft I extends from the bottom of the mounting frame to the dial and is connected to the gear mechanism inside the dial; a magnetic steel I is fixed to the bottom end of the gear shaft I, and the magnetic steel I can drive the gear shaft to rotate with the magnet; a snap ring is installed above the case, a transparent cover is installed on the snap ring, and a closed cavity is formed between the transparent cover and the inner cover.

[0006] The copper-sealed Internet of Things water meter of the present invention adds a copper inner cover inside the outer cover, so that a closed cavity is formed between the inner cover and the glass transparent cover, thereby increasing the waterproofness of the water meter. In addition, copper has better waterproof performance than plastic. Even if it is in a humid environment for a long time, water molecules will not pass through the copper inner cover into the meter core, thereby increasing the service life of the water meter.

[0007] Preferably, four pointers are installed on the dial, each pointer is connected to the gear shaft II of the gear mechanism, a reflector is fixed to the bottom of any one of the four gear shafts II, and a photoelectric switch corresponding to the reflector is fixed on the circuit board, and water metering is achieved by adopting the principle of photoelectric signal acquisition.

[0008] Preferably, a magnet II is fixed to the bottom of any one of the remaining three gear shafts II of the four gear shafts II, a Hall sensor corresponding to the magnet II is fixed on the circuit board, and water metering is achieved by adopting the pulse acquisition principle.

[0009] Preferably, a gasket is installed between the inner cover and the transparent cover to increase the waterproofness between the inner cover and the transparent cover.

[0010] Preferably, the upper edge of the outer cover extends outward to form a flange, the lower end of the flange abuts against the upper edge of the watch case, and the upper end abuts against the lower edge of the transparent cover, and sealing rings are installed between the lower end of the flange and the upper edge of the watch case and between the upper end of the flange and the lower edge of the transparent cover to further increase the waterproofness of the water meter.

[0011] The beneficial effects of the present invention are embodied in that: the Internet of Things water meter adopts double waterproofing, that is, sealing rings are added at the upper and lower ends of the outer cover flange to prevent water from entering the outer cover from the inside of the case, and a copper inner cover is added inside the outer cover to form a closed cavity between the inner cover and the transparent cover, so that the electronic part (that is, the signal acquisition and data transmission part) and the water meter indication mechanism are integrally encapsulated in the closed cavity, so that the water meter indication structure and the electronic part are not in contact with the water in the pipeline, and the indication part is not affected by water, thereby achieving a true IP68 protection level; at the same time, the signal of the Internet of Things water meter adopts a hybrid metering mode of a pulse acquisition structure and a photoelectric signal acquisition structure, which has a simple structure and can improve the accuracy and precision of water volume measurement.
